Uber Software Developer interview questions

Very helpful recruiter and totally arrogant interviewer (also confirmed by some current and ex-employee that a lot of people from Uber are considering themselves as the smartest guys in the universe), although he was speaking polite and friendly, he provided feedback: “not sure about naming variables” (that was rejection reasons) even if I have solved problem in optimal time and space complexity. Was white board problem solving test.

This was for ATG group. Stages: recruiter phone screen, technical phone screen (w/ online coding ), hiring manager call, onsite interview (5 different sessions, plus lunch). Recruiter didn't call me at scheduled time for phone screen. had to reschedule. Technical phone screen had to be rescheduled due to miscommunication between recruiter and interviewer. Process was very slow (about 2.5 months). Feedback/responses from recruiters was slow (sometimes 1-2 weeks without hearing anything at all). Process felt unnecessarily bureaucratic at times (had interactions with SIX different recruiters, not including interviewers.)
